FOREWORD

This Indian Standard ( Third Revision ) was adopted by the Bureau of Indian Standards, after the draft
finalized by the Sanitary Appliances and Water Fittings Sectional Committee had been approved by
the Civil Engineering Division Council.

This standard was first published in 1963 and the first and second revisions were issued in 1967 and
in 1979 respectively. In this revision changes found necessary in the light of the comments made by
users and improvements made by the vitreous sanitary ware industry have been incorporated.

This standard contains clause 4.1.1 which calls for an agreement between the purchaser and the
supplier. The waste fitting made of vitreous china has been deleted from this standard as neither it is
manufactured nor it is normally used.

In the formulation of this standard due weightage has been given to international co-ordination among
the standards and practices prevailing in different countries in addition to the practices in the field in
this country. Dimensions of waste hole have been aligned with EN 32 'Wallhung Wash Basins:
Connecting Dimensions'; issued by European Committee for Standardization.

The composition of the technical committees responsible in the formulation of this standard is given
in Annex A.

For the purpose of deciding whether a particular requirement of this standard is complied with, the
final value, observed or calculated, expressing the result of a test or analysis, shall be rounded
off in accordance with IS 2 : 1960 'Rules for rounding off numerical values ( revised y. The number of
significant places retained in the rounded off value should be the same as that of the specified value in
this standard.

3 GENERAL REQUIREMENTS

The general requirements relating to termino-
logy, material and manufacture, glazing,
defects, minimum thickness, tolerances, per-
formances and methods of tests shall conform
to IS 2556 ( Part 1 ) : 1994.

4 SIZES

4.1 Sinks shall be in the following sizes
( see Fig. 1 ):

400 X 250 X 150 mm

600 X 450 X 200 mm

4.1.1 The sinks may be made in other sizes
where so agreed between the manufacturer and
the purchaser. However, the tolerances on
dimensions and waste outlet hole dimensions
shall be as allowed in this standard.

5 DIMENSIONS AND TOLERANCES

The sink shall conform to the dimensions given
in Table 1, read with Fig. 1.

6 CONSTRUCTION

6.1 The sink shall be of one-piece construction
including overflow, where provided.

6.2 The sink shall have a circular waste hole
through which liquid content of the sink shall

into the waste hole. The waste hole shall be
bevelled internally and shall meet the dimen-.
sions given in Table 2.

6.2.1 Sinks shall be provided with waste outlet
fittings conforming to the requirements laid
down in IS 2963 : 1979.

sink shall be provided with a rim.

the

6.4 Where integral overflow is provided, the
projection on account of overflow connection
to the waste outlet hole of the sink shall be
over and above the dimensions H. Where
integral overflow is not provided, the projection
at the outlet shall be not less than 15 mm.

NOTE — The dimension H shall be measured at the
end opposite to waste hole, as shown in Fig. 1.

6.4.1 Where an overflow hole is provided, it
shall be of 25 mm diameter.

7 FINISH

Inside surfaces of sinks shall be uniform and
smooth in order to ensure an eflScient draining.

8 SAMPLING, PROCESS INSPECTION AND
LOT INSPECTION

8.1 The recommended method of sampling,
process inspection and lot inspection of
laboratory sinks shall be as given in IS 9140 :
1985.
